Isolator for Charging Start and Auxiliary Lithium Battery
Published 12/19/2022
Question:
I have a 100 Amp hour LiFePO4 battery in my RV and it will not start my onboard Onan generator due to the generator pulling over 100 Amps to start and the BMS turning the battery off. I was thinking of adding a starter battery for the generator but not sure how to charge it since different Lithium batteries should not be run in parallel and to charge them they would need to be in parallel. Any suggestions? Isolator? Capacitor? thanks

We have isolators like the Deka part # DW08771 which was designed for this situation. It will charge both batteries while also keeping them separate which means they wouldn't be in parallel.
